In May 2019, there were two Euro air workshops held in Da Nang (in the Middle of Vietnam) and in Hanoi. The purpose was to communicate with potential clients and clients (including investors, MEP contractor and M&E engineering companies) both in the North and in the Middle of Vietnam. In the workshops, updated information of Euro air and its application in Vietnam were given to client to have better understanding on the textile ducts and textile duct technologies. The workshops also stood a good chance to provide proper answer for client’s comments  and queries.
